I bought my first PINsub product for my Elvira and wanted to share how good the product is. For background, all my games are currently hooked up with alligator clips running from the cabinet speaker to the Polk psw10 subs. The install of the pinnovators product is literally about 2 mins. Plug into the game’s board, run wire to external sub. I was skeptical that I’d hear any difference, but it was clearly obvious with deep and cleaner bass. It’s hard to explain, but it’s like hooking a sound system up with a cheap pair of speakers vs a good pair, you definitely notice. The downside here is that now I have one, I want it for all my games. Not only that, but customer service is great, very responsive helping me get what I need.
